AIR WAEHER.

Application filed January 5, 1923. Serial No. 610,952.

of Illinois, have invented certain new and useful Improvements in Air Washers, of-

which the following is a specification.

This invention relates to improvements in air moistening, dehumidifying and purifying apparatus, and it consists in certain peculiarities of the construction, novel orrangement and combination of the various parts thereof as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is the production of an air washer, or up parotus of the above mentioned ,general character, which shall be compact in form, simple and inexpensive in construction, and highly efficient in operation, wherein and whereby a Continuous current of air, which may or may not previously, or afterwards, have its temperature raised or lowered, is beneficially treated and caused to flow through a conduit or casing and be delivered to a suitable place or places for any desired urpose. v Another o ject is the provision of means comprising 2t portion of the apparatus, for the saturation of the volume of air as it enters the intake portion of the conduit therefor, without the necessity of employing a pump, and means for ope sting tie some in order to maintain constant pres sure for spraying water. I

The invention contemplates us a further object thereof, rotary means withinthe 0011" duit, for co-operetion with the volume or current of humidified air for dehumidifying the some and for the elimination therefrom of impurities such as dust and the like.

Gther objects and advantages of the in vention will be disclosed in the following description and explanation.

In the accompanying drewing,--

Fig. 1 is a central longitudinal view partly in section and partly in elevation of an air Washer embodying the invention.

Fig. 2- is an enlarged perspective view of a portion of the rotary eliminator for re moving water and impurities from air as it passes through the apparatus, and "Fig. 3 is an enlarged plan view partly in section end; pertly'in elevation token on 'mitting power from a motor,

line 3-3 of Fig. 2 as indicated by the arrows.

Corresponding numerals of reference re-'- for to like parts throughout the difierent views of the drawing.

Referring now more particularly to Fig. 1 of the drawing, the reference numeral 5 designates the rotary shaft of the apparatus which is horizontally journeled near one of' its ends on an upright support 6 and ne'er its other end in any suitable support. but in the present instance is shown as being transversely journeled in the blower cesin the apparatus.

This shaft may be driven bv any suitable means such as by apply,

lug power to a pulley 8 thereon through the medium of a belt employed for transnot shown, or the like.

Mounted within the blower casing 7 is a fun 9 of the ordinary or any preferred construction, which isemployed' tocreete and maintain a current of air through the,

casing of the apparatus and to conduit or force said current through an outlet 10 of the blower casing, from whence it may be conducted to any suitable place or places and used for the desired purpose.

As shown, a cylindrical casing, designated as a. whole by thenumeral 11, surrounds the shaft 5 end by preference is located concentrically with respect to the same. This casing has one of its ends, which will be tcrmedthe inlet end thereof, contracted and open for the entrance of air as shown in Fig 1 of the drawings. The other end of the casing 11 has an inwardly extended annular flange 12; through the opening provided by said flange is extended a. forwardly flared member 13, the outer portion of which member fits closely around an annular iii-take extension 14- with which the blower casing "T is provided on its front surface. The casing 11 is by preference mode of two sections 15 of air as it passes through the casing 11 into the rotary eliminator of the upperetus.

too

This eliminator comprises a hub 18 secured to the shaft 5 so as to rotate therewith and 26 is of greater width than the vanes 19 and shown, project at their free ends beyond the.

has its front end overlapping the rearwardly tapered portion of the deflecting collar or flange 17, while its rear end extends some distance rcarwardl y of the rear edges of the blades 19 and terminates at the front end of the flared member 13 but outwardly CO11C 1I tric therewith.

Each of the vanes or blades 19 has on its rear edge ateach side. thereof, a longitudi-- nally extended ledge or batlle member 21, which extend from the hub 18 to points near the inner surface of the rim orannulus of the eliminator Wheel. The outer ends of each pair of the members 21 are transversely connected by means of a. cleat or bailie member 22 which rest on the inner surface of the rim 20 and may be secured thereto as well as to the members 21 in any suitable manner. At one of the corners between the outer ends of each pair of blades 19 an opening 23 is rovided, in each of which openings is located a tube 24 which have the same inclination as that of the blades or vanes 19 and as rear endof the rim 20 of the eliminator Wheel. 1

The front end of the shaft 5 is provided with a longitudinally extended opening 25 and at the inner end of said opening with a series of spaced perforations 26 which are inclined forwardly from their inner ends as will be readily understood by reference to Fin. 1 of the drawings. Fitted in the outer on of the opening 25 of the shaft 5,'is a Water supply pipe 27 which may have communication With a supply of water under pressure such as that ordinarily afforded by the Water mains used in cities, not shown.

it will beunderstood that't-he vanes of the eliminator Wheel, as well as those of the fan 9 of the blower, are so pitched as to produ e and maintain current of air through the casing 11, eliminator wheel, flared member 13, and inlet extension 14 of the blower, which constitute the conduit of the apparatus, by suction action, and that as the eliminator wheel and fan 9 are rotated in the same direction by the shaft 5, there will be but little friction incident to the passage of the current of air through the blades of the eliminator wheel. 1

From the foregoing and by reference to the drawing, it will be readily understood and clearly seen that the operation of. the device is simple and as follows:

Assuming that the fan and eliminator wheel are rotated on the shaft 5 and that water under pressure is admitted through the water pipe 27 to the opening 25 in said shaft, it is manifest that a quantity of water will be discharged through the perforations 26 at the inner end of the opening 25 in the shaft 5, and that as said perforations are inclined so as to force the jets of water forwardly, a revolving sheet-like. spray will be produced through which air entering the inlet end of the casing must pass and become moistened or saturated. in the further movement of the currentof air through the casing, the same will strike the rapidly turning blades 19 and by reason of centrifugal action as well as its forward movement, will be forced against the ledges or ballle members 21 and 22 and out through the tubes 24; from which water and impurities will be discharged into the space between the rear end of the casing 11 and the flared member 13, thus permitting the purified, and to a certain extent (lo-humidified, air to pass through the member 13, and extension 1 1, into the blower casing 7 and from thence through its discharge opening 10 to any desired point. t

As some water will collect in the lower front portion of the casing 11 frlln'the spray, said part of the casing is provided with an outlet 28, and the rear lower portion of the casing 11 is provided with ans other outlet 29 for the discharge of water collected by the eliminator wheel and dis charged by the tubes 24: thereof. 7

As the ledges or battle members 21 and 22 are located at forwardly inclined angles to the blades 19 and rim 20 respectively, it is manifest that they will provide gutters or troughs for the water'and impurities collected thereby which will be guided to the tubes 2 1 for discharge.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In an air washer, the combination with a casing having one of its ends open for the entrance of air, of means near its open end for spraying water, an eliminator wheel mounted for rotation Within said casing for co-operation with the moistened air, said wheel con'iprising radial blades set at an angle to its axis. and'prQVide'dwith a peripheral rim connecting the outer ends of said blades, a ledge or bathe member on the rear edge at each side of each of said blades, a ledge or bafllc inember connecting each pair of said blades transversely and resting on the inner surface of said rim, an outlet at one of the cornersbetWeen the outer ends of llll) iae sesame ing a current of air t rough said casing.
